proxmox-backup-client restores incomplete snapshot when backup is still running

[MLTE]

Hi,

I noticed unexpected behavior with proxmox-backup-client during restore tests and would like to clarify whether this is intended or a bug.

Environment / Setup​

• Proxmox Backup Server 3.4.8
• Proxmox backup client version: 4.1.1
• I use one host per namespace.
• In this case, the namespace is: hosts/postgres-server
• A backup job is running for that host while I attempt a restore on a test server.

Listing Available Backups​

When I list the available backups:

proxmox-backup-client list --ns hosts/postgres-server
The latest snapshot shown is:
host/postgres-server/2026-02-09T21:00:01Z

Restore Command Used​

I run the restore without specifying a snapshot name:
proxmox-backup-client restore host/postgres-server postgres.pxar /mnt/test --ns hosts/postgres-server
Since I do not define a specific snapshot, the command is expected to use the latest available snapshot of the group.

Observed Behavior​

Instead of restoring the latest completed snapshot (2026-02-09T21:00:01Z), the client attempts to restore a newer snapshot:
2026-02-10T21:00:02Z
However, this snapshot is still being created (the backup task is not finished yet), and the restore fails.

Question​

Is this behavior expected?

If so, what is the reasoning behind selecting a snapshot that is still in progress?

If not, would it make sense to adjust the logic so that, when no snapshot is explicitly specified, only fully completed snapshots are considered?

Thanks in advance for your feedback.
